  • Patent number: 7131435
    Abstract: In step 400, microcomputer 12 calculates a temperature change amount ?T1 of ignition coil FC caused by the heat generating from the ignition coil FC, based on a previous calculated temperature T(n?1) of ignition coil FC and an engine rotational speed. In step 410, the microcomputer 12 calculates a temperature change amount ?T2 of ignition coil FC caused by the heat received from the engine, based on the previous calculated temperature T(n?1) of ignition coil FC and a cooling water temperature of the engine. In step 420, the microcomputer 12 calculates a temperature change amount ?T3 of ignition coil FC caused by the heat released to the outside, based on the previous calculated temperature T(n?1) of ignition coil FC and an intake air temperature of the engine. Then, in step 430, the microcomputer 12 calculates a present ignition coil temperature T(n) based on these change amounts ?T1, ?T2, and ?T3.

  • Patent number: 6618666
    Abstract: In an ECU for vehicles, a microcomputer operates with a main power from a battery, and a clock IC operates with sub power from the battery and measures time continuously irrespective of whether the microcomputer is operating. The microcomputer stores time data of the clock IC just before the supply of main power is turned off, and calculates a soak time or engine stop period from the stored time data and a current time data of the clock IC only after the supply of main power is turned on again and engine cranking is completed. This soak time represents the engine stop period. Operation of a cooling water temperature sensor or the like is checked by using the sensor output in relation to the calculated soak time.

  • Patent number: 6556901
    Abstract: In an ECU for vehicles, a clock IC operates with sub power and measures time continuously irrespective of whether a microcomputer is operating. The microcomputer determines whether the clock IC has been reset on the basis of a history indicating that the sub power has fallen below a data holding voltage of an SRAM which also operates on the sub power. Alternatively, the microcomputer determines whether the clock IC has been reset by checking data held in the SRAM. The microcomputer determines failure of a water temperature sensor from a soak time calculated from time data from the clock IC and a detection value of the water temperature sensor on restarting of the engine. When the clock IC has been reset, the microcomputer prohibits this failure determination of the water temperature sensor.
